Reaksiyalar zanjiri: ZnS →(+O₂) A →(+O₂, kat) B →(KOH) C. A modda gaz, C modda o‘rta tuz. C moddaga bariy xlorid eritmasi qo‘shilganda qanday modda cho‘kmaga tushadi? BaSO₃ BaSiO₃ AgCl BaSO₄ Show answer 📝 Detailed explanation 2ZnS+3O₂→2ZnO+2SO₂ (A=SO₂); 2SO₂+O₂→2SO₃ (B=SO₃); SO₃+2KOH→K₂SO₄+H₂O (C=K₂SO₄). K₂SO₄+BaCl₂→BaSO₄↓+2KCl.
